# BZX84C15

**hongjiacheng** · Zener Diodes · SOT-23

BZX84C15 from hongjiacheng, in a SOT-23. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | A | passive | Anode of the zener diode, shown connected to the diode symbol in the SOT-23 function diagram. |
| 2 | NC | unconnected | No internal connection; the function diagram shows pin 2 with no connection to the diode. |
| 3 | K | passive | Cathode of the zener diode, shown connected to the diode symbol in the SOT-23 function diagram. |
